A companion class, QgsLayoutItemGuiRegistry, handles the GUI behavior of layout items.

New in version 3.0: Enums

addLayoutItemType(self, metadata: QgsLayoutItemAbstractMetadata) → bool¶: Registers a new layout item type. Takes ownership of the metadata instance.

addLayoutMultiFrameType()

addLayoutMultiFrameType(self, metadata: QgsLayoutMultiFrameAbstractMetadata) → bool¶: Registers a new layout multiframe type. Takes ownership of the metadata instance.

addLayoutItemType()

childEvent()¶

connectNotify()¶

createItem(self, type: int, layout: QgsLayout) → QgsLayoutItem¶: Creates a new instance of a layout item given the item type, and target layout.

See also

createMultiFrame()

createMultiFrame(self, type: int, layout: QgsLayout) → QgsLayoutMultiFrame¶: Creates a new instance of a layout multiframe given the multiframe type, and target layout.

createItem()

customEvent()¶

disconnectNotify()¶

isSignalConnected()¶

itemMetadata(self, type: int) → QgsLayoutItemAbstractMetadata¶: Returns the metadata for the specified item type. Returns None if a corresponding type was not found in the registry.

See also

multiFrameMetadata()

itemTypes(self) → Dict[int, str]¶: Returns a map of available item types to translated name.

multiFrameMetadata(self, type: int) → QgsLayoutMultiFrameAbstractMetadata¶: Returns the metadata for the specified multiframe type. Returns None if a corresponding type was not found in the registry.

See also

itemMetadata()

multiFrameTypeAdded¶: Emitted whenever a new multiframe type is added to the registry, with the specified type and visible name. [signal]

populate(self) → bool¶: Populates the registry with standard item types. If called on a non-empty registry then this will have no effect and will return False.

receivers()¶

resolvePaths(self, type: int, properties: Dict[str, Any], pathResolver: QgsPathResolver, saving: bool)¶: Resolve paths in properties of a particular symbol layer. This normally means converting relative paths to absolute paths when loading and converting absolute paths to relative paths when saving.

sender()¶

senderSignalIndex()¶

timerEvent()¶

typeAdded¶: Emitted whenever a new item type is added to the registry, with the specified type and visible name. [signal]
